Phoenix is by far the most populous city in Arizona and it's twice the size of Tucson. Copper, climate, citrus, cattle and cotton continue to be a driving force for the economy. Like most major cities, Phoenix freight shipping options include all modes from trucking to air. Foods that cannot grow in Arizona's dry climate are among the city's top most imported goods.

Houston freight shipping services include a heavy mix of ocean and air, as well as truck and rail due to its strong road infrastructure, two airports and a busy ocean port. Houston has the highest population of any Texas city and it is also the fourth largest city in the entire US. Rich in commercial enterprise, Texas leads the nation in industries like agriculture, energy, electronics, and many more.
